Iris tridentata vs. nutrients

Iris tridentata actually grows in acid bogs and seeps with pitcherplants and
Hymenocallis henryae here in the panhandle of Florida.  What the specifics
are of why they are able to I can't say for sure, but quite unlike the other
Iris you mentioned, I. tridentata seems much happier in cultivation in
similar conditions.

I built a bog bed specifically for carnivorous plants this spring (about
3 months ago).  My Sarracenia pitcher plants are happy as could be.  I
also transplanted a couple Iris tridentata in there.

Now, 3 months later, the tridentata are thriving.  I am gobsmacked how
much better the I. tridentata are doing in that nutrient poor bog bed,
than in the other (equally soggy) spot the others are in.

What's up with that?!

Would other irises respond like that?  I. fulva?  I. brevicaulis?

I've always thought of irises as heavy feeders, thriving on nutrients.
I can't stop scratching my head over this nutrient poor bed and my super
happy tridentatas.
